Look up "The Manhattan Project"
Manhattan Project was the setup in 1942 for the U.S
The Manhattan project was a project initiated by the US government that ended up creating the atomic bomb. The project was managed by Gen. Leslie Groves.
Well, it was the Manhattan project that allowed (or more accurately invented/ came up with) the atomic bomb that killed millions in Japan to force them into surrender.
code name for the secret United States project set up in 1942 to develop atomic bombs for use in World War II
The Manhattan Project achieved its goal up to the bombings on Japan. That was the code name.
The scientists did not "give up" on the Manhattan Project. They accomplished their goals of developing three atom bombs. The Project ended at the end of the war. The workers went home and much of the "little towns" were taken down. There was no need for the project to continue after the war. It cost 2 billion dollars back then to create the three bombs so the government would not fund it any further when there was no need for further work.
While considerable scientific and theoretical work had begun as early as1939, the Army Corps of Engineers set up the Manhattan EngineerDistrict in August of 1942 and advanced Colonel Leslie R. Groves to therank of Brigadier General one month later and placed him in charge.Groves was responsible for establishing the Oak Ridge site and LosAlamos, but the scientific effort was led by J. Robert Oppenheimer.
Unfortunately this is not true. Every project has an end and every project life cycle has an end too. The last phase of any projects life cycle is the project closure/closing phase where the project is wrapped up and closed.
The top secret program to build an atomic bomb was called the Manhattan Project. It was so secret the top Generals and Admirals did not know about it. The people who worked on the project often did not know what they were working on. All the workers lived in places that were developed from the ground up and they could not talk about what they were doing. Even Vice President Truman did not know about it until after President Roosevelt died.
No, the idea came up very early in the Manhattan Project in discussions involving several people.
